AUGUST P. J. BOSSEL, OF VIRGINIA CITY, NEVADA.

BENCH-PLANE.

SPECIFICATION forming part of Letters Patent No. 231,990, datedSeptember '7, 1880. Application filed June 29, 1880. (No model.)

To all whom it may concern Be it known that I. AUGUST I. J. BossEL, ofVirginia City, in the county of Storey and State of Nevada, haveinvented a new and useful Improvement in Planes, of which the fol"-lowing is a specification.

My invention is more particularly intended for planes used in rabbeting,but it is applicable to planes of various kinds.

The invention consists, first, in a novel construction, arrangement, andcombination, with the plane-bit, of a toothed plate or rack, and apinion for adjusting the bit, and a wedge for holding it when adjusted;and, further, in a novel arrangement of the handle of the plane anddevices connected therewith for adjusting said handle at diii'erentpositions.

In the accompanying drawings, Figure l is a longitudinal verticalsection of a plane embodying my improvements. Fig. 2 is a top View of aportion of the same with the bit and wedge removed. Fig. 3 is a rear-endview.

Similar letters of reference indicate corresponding parts.

The plane A is preferably made of metal, and the throat a may be of theusual description. At the top of the throat a is an upwardly-projectinglog or plate, B, in which is journaled a short shaft, the front end ofwhich carries a pinion, D. The rear end of this shaft may have a milledknob attached directly to it, but as here represented it carries agearwheel, E, with which engages another gearwheel, G, carried by oneend of a short shaft journaled in said plate B. and having at its otherend a milled knob, H.

In a recess, 1), on the front side of the plate ted plate It, and the lng 10,111 combination with B, Works a sliding rack, J, with which thepinion D engages. Near the upper end of the rack J, and on the frontside thereof, is a pro jecting pin or stud, s, which engages with a holein the plane-bit K, near the upper end thereof. By turning the pinion Din one direction or the other the bit K is adjusted up or down in orderto regulate its out.

The wedge L is provided with a thumbscrew, m, which passes through itand bears against the front surface of thebit K. When the bit has beenadjusted to the desired position the screw m is tightened so as to holdthe bit firmly in place by the combined pressure of said screw and ofthe lower end or point of the wedge. By the means above described thebit may be readily adjusted with exact nicety without the use of ahammer, as in the ordinary plane.

The handle P, instead of being rigidly attached to the plane, is pivotedat 12 between a quadrantal plate. 1%, extending upward from the planenear the rear end thereof, and a lug, to, in front of said plate It.

A thumb-screw, T, passes through an are shaped slot, '0, in the plate R,and through the handle P above the pivot 11, and bears against the lugw, and thus holds the handle firmlyin position. When the plane is usedin a corner or near a surface where space for the handle and the hand islimited the handle P may be inclined, as indicated in dotted lines inFig. 3, and held firmly in position by the screw T.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. A plane consisting of the body A,provided with the upwardly-extending plate B, having the recess 1), therack J, sliding in said recess, the bit K, having its shank elongatedand connected to said rack by the pin or stud s, the pinion D, operatingsaid rack, and the wedge L, provided with the thumb-screw m,substantially as herein described.

2. The handle P, pivoted at p, the are-slotthe thumb-screw T, as and forthe purpose specified.
